Description

Technical Field

[0001] This utility model relates to the field of conductive paste technology, and in particular to a multifunctional conductive paste preparation device. Background Technology

[0002] Conductive paste is a material formed by uniformly adding conductive powder to a binder and then curing it. It is used in the formation of electronic circuits, the formation of electrodes for electronic components, the lead-out of leads, and the formation of circuit contacts.

[0003] The conductive slurry contains particles of various sizes and shapes. These particles tend to aggregate due to interactions such as surface tension and electrostatic attraction, forming agglomerates. The presence of particle agglomerates reduces the flowability of the material, increases the difficulty of transportation and handling, and leads to uneven particle distribution, affecting product performance and quality. It also reduces the utilization rate of surfactants, catalysts, etc.

[0004] Therefore, the preparation of conductive paste requires processes such as dispersion and demagnetization. In the existing technology, these processes are usually carried out separately, and the paste must be processed by equipment such as dispersion tanks and demagnetization tanks in sequence before a qualified conductive paste can be prepared. This seriously affects the preparation efficiency of conductive paste. In addition, the existing centralized dispersion methods are singular and not conducive to improving dispersion efficiency. Utility Model Content

[0030] like Figure 1-3The multifunctional conductive slurry preparation device shown includes a container tank 1, an ultrasonic disperser, a first drive motor 2, and a magnetic stirring paddle 21. The container tank 1 is used to contain conductive slurry and includes a tank body 11 and a tank cover 12, which are detachably connected to the tank body 11. The ultrasonic disperser is located at the bottom of the tank body 11 and is used to emit ultrasonic waves to disperse particle agglomerates in the conductive slurry. The first drive motor 2 is located on the tank cover 12, and the magnetic stirring paddle 21 is rotatably located inside the tank body 11 and is connected to the drive shaft of the first drive motor 2. It should be noted that an ultrasonic disperser typically consists of a generator, a transducer, and a reflector. The ultrasonic waves emitted by the ultrasonic disperser can break up particle agglomerates in the conductive slurry, thereby dispersing them and improving the uniformity of the conductive slurry. The first drive motor 2 can drive the magnetic stirring paddle 21 to rotate at a low speed to stir the conductive slurry, keeping it in motion and preventing sedimentation, which can further improve the uniformity of the conductive slurry. In addition, the magnetic stirring paddle 21 is made of magnets, which can adsorb magnetic impurities in the conductive slurry to achieve demagnetization. Furthermore, the magnetic stirring paddle 21 can contact different areas of the conductive slurry when rotating, thereby improving the demagnetization effect.

[0031] It should also be noted that ultrasound refers to sound waves with frequencies higher than 20kHz. When it propagates through matter, it produces a series of complex physical effects, one of which is ultrasonic dispersion. Ultrasonic dispersion utilizes the mechanical vibration energy of ultrasound to break up and disperse particles or solid particle agglomerates, making them uniformly dispersed in a liquid. When ultrasound passes through a substance, it causes mechanical vibrations within the substance. These vibrations are caused by the ultrasound waves transmitted to the molecules and particles within the substance. Under the action of ultrasound waves, the molecules and particles in the substance are subjected to periodic compression and expansion forces, resulting in effects such as shearing forces, impact forces, and vortex flows. During the propagation of ultrasound waves, relative displacement between molecules within the substance is caused, forming shearing forces. These shearing forces can penetrate the liquid layer and shear particle agglomerates apart. When ultrasound waves propagate in one direction, high-density and low-density regions are formed in the direction of sound wave propagation. When particle agglomerates are present in the liquid, the agglomerates are impacted into the high-density regions, generating impact forces that can break up the particle agglomerates. When ultrasound propagates in one direction, it creates a periodic compression and expansion process in the liquid, thereby generating vortex flow. Under the action of vortex flow, particle agglomerates are subjected to local vibration and shear force, which causes them to break up.

[0032] The beneficial effects of this invention are as follows: the ultrasonic waves emitted by the ultrasonic disperser can break up the particle agglomerates in the slurry; the first drive motor 2 can drive the magnetic stirring paddle 21 to stir the slurry, so that the slurry is more dispersed and uniform, improving the dispersion efficiency and quality; at the same time, the magnetic stirring paddle 21 can also adsorb magnetic impurities in the slurry, completing the dispersion and demagnetization processes in one go, which greatly improves the preparation efficiency of conductive slurry.

[0033] Please refer to Figure 2 In one possible implementation, the magnetic stirring paddle 21 has blades with through holes. It should be noted that the magnetic stirring paddle 21 is in a "string" shape. This design increases the contact area between the magnetic stirring paddle 21 and the conductive slurry, thereby improving the adsorption efficiency of the magnetic stirring paddle 21 for magnetic impurities and enhancing the demagnetization effect.

[0034] Please refer to Figure 1 In one possible implementation, the system further includes a second drive motor 3, an annular guide rail 31, and a conveyor frame 32. The second drive motor 3 is mounted on the annular guide rail 31, and the conveyor frame 32 is slidably mounted on the annular guide rail 31. The drive shaft of the second drive motor 3 is connected to the conveyor frame 32, and the container 1 is connected to the conveyor frame 32. It is easily understood that the annular guide rail 31 is circular, and the conveyor frame 32 is arranged along the annular guide rail 31. Specifically, the second drive motor 3 can drive the conveyor frame 32 to slide along the annular guide rail 31, thereby causing the container 1 to move slowly with the conveyor frame 32.

[0035] Please refer to Figure 1 and Figure 2 In one possible implementation, the can lid 12 is provided with a connecting post 121, and the connecting post 121 has a connecting pipe 13, which is connected to the conveyor frame 32. It should be noted that the can lid 12 has connecting posts 121 on both sides, and there are two connecting pipes 13, which are connected to the two connecting posts 121 respectively. The conveyor frame 32 has a connecting node, and both connecting pipes 13 are connected to the connecting node. The two connecting pipes 13 and the can lid 12 form a triangle, which makes the structure more stable and helps to improve the connection strength between the can 1 and the conveyor frame 32.

[0036] Please refer to Figure 3In one possible implementation, there are multiple container tanks 1, which are evenly spaced and suspended on the conveyor frame 32. It should be noted that the conveyor frame 32 has multiple connection nodes, and each container tank 1 is connected to each connection node in a one-to-one correspondence. Specifically, in this embodiment, there are four container tanks 1, each spaced 90° apart. When the second drive motor 3 drives the conveyor frame 32, the four container tanks 1 move cyclically along the circular guide rail 31. This design facilitates material feeding. The conductive slurry needs to be conveyed into the container tanks 1 by the feeding device. The circular guide rail 31 is positioned close to the feeding device, allowing the four container tanks 1 to pass through the feeding port of the feeding device sequentially as they rotate. This allows the feeding device to sequentially convey conductive slurry to the four container tanks 1, while also facilitating the feeding and mixing of different slurries.

[0037] Please refer to Figure 1 In one possible implementation, a slurry outlet channel 111 is provided on the inner bottom of the tank body 11, and a slurry outlet switch 112 is provided at the opening of the slurry outlet channel 111. It is easy to understand that after the conductive slurry is prepared in the receiving tank 1, it needs to be transported to the next process. The connection between the slurry outlet channel 111 and the tank body 11 is located at the bottom center of the tank body 11, and the slurry outlet channel 111 is lower than the cavity of the tank body 11, so that the conductive slurry automatically flows into the slurry outlet channel 111 under its own weight, which greatly facilitates the outflow of the conductive slurry. The slurry outlet switch 112 can open / close the opening of the slurry outlet channel 111.

[0038] Please refer to Figure 1 In one possible implementation, an ultrasonic flow meter is provided at the lower end of the tank 11, corresponding to the slurry outlet channel 111. The ultrasonic flow meter is used to detect the flow rate of conductive slurry passing through the slurry outlet channel 111. It should be noted that the ultrasonic flow meter is a flow meter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the velocity of the sound wave in a stationary medium. It mainly consists of a transducer and a converter. The ultrasonic flow meter can perform non-contact measurement. The clamp-on transducer ultrasonic flow meter can be installed without stopping the flow and cutting off the pipe; the transducer can simply be installed outside the existing pipeline.

[0039] Please refer to Figure 1 In one possible implementation, the tank 11 is provided with a mass display screen 14, which is used to display the detection value of the ultrasonic flow meter. It should be noted that when the fluid volume is expressed in mass, it is called mass flow rate. The mass display screen 14 can display the mass of slurry flowing out of the receiving tank 1. Therefore, the user can control the slurry weight by observing the mass display screen 14 to turn the slurry outlet switch 112 on / off.

[0040] Please refer to Figure 1In one possible implementation, the tank 11 is equipped with an ultrasonic display screen 15, which displays the ultrasonic time of the ultrasonic disperser. It should be noted that the ultrasonic disperser does not need to run continuously, but only needs to run at intervals for a certain period of time. Therefore, the user can observe the running time of the ultrasonic disperser through the ultrasonic display screen 15 and turn it off when the running time of the ultrasonic disperser is met.

[0041] Please refer to Figure 2 In one possible implementation, a first locking part 122 is provided on the side wall of the can lid 12, and a second locking part 113 is provided on the side wall of the can body 11. The first locking part 122 and the second locking part 113 are fixedly connected. Specifically, the can lid 12 has a first locking part 122 on both sides, and the can body 11 has a second locking part 113 on both sides. The two first locking parts 122 correspond to the two second locking parts 113 respectively. The first locking parts 122 and the second locking parts 113 can be fixedly connected by using fixing pins, fastening bolts, etc., or the first locking parts 122 and the second locking parts 113 can be locked together.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
